Description

Technical Field

[0001] This utility model relates to the field of turning technology, specifically a turning device for machining shaft pins. Background Technology

[0002] A lathe tool is a cutting tool with a single cutting part used in turning operations. Lathe tools are among the most widely used cutting tools in machining. The working part of a lathe tool is what generates and handles chips, including the cutting edge, structures that break or coil the chips, spaces for chip removal or storage, and channels for cutting fluid. A pin, or shaft, is a standardized fastener that can provide both static fixation and relative movement with the connected parts. It is mainly used at the hinge joints of two parts to form a hinge connection. Pins are usually locked with cotter pins, ensuring reliable operation and easy disassembly.

[0003] However, existing turning equipment used for machining shaft pins typically provides additional support by installing a center rest on the machine tool's track when turning slender shaft pins, thereby suppressing turning vibrations. However, the process of installing the center rest is relatively complicated, resulting in a slow installation speed and poor efficiency in shaft pin machining. Utility Model Content

[0004] This invention provides a turning device for machining shaft pins, which not only provides support for shaft pins of different diameters, but also maintains the smoothness of the machined surface, thus solving the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a turning device for machining shaft pins, including a machine housing, a chuck installed on one side of the top of the machine housing, a shaft body disposed inside the chuck, a center pin disposed at one end of the shaft body away from the chuck, the center pin being slidably connected to the machine housing, a feed box disposed on one side of the center pin, the feed box being slidably connected to the machine housing, a cutter head fixedly connected to the top of the feed box, a shock-absorbing mechanism disposed on one side of the cutter head, and a conveying mechanism disposed on one side of the feed box.

[0006] Preferably, the shock-absorbing mechanism includes a fixed box fixedly installed on one side of the top of the feed box. A lifting rod is installed inside the fixed box. Two fixed blocks are fixedly connected to the fixed box near the lifting rod. The lifting rod is slidably connected to the fixed blocks and the fixed box. A drive wheel is rotatably connected to the top of the lifting rod. Inclined blocks are fixedly connected to both sides of the middle of the lifting rod. A curved rod is installed on the side of each inclined block away from the lifting rod. Both curved rods are rotatably connected to the fixed box via torsion springs. A driven wheel is rotatably connected to the bottom of each curved rod. The driven wheel is coupled to the inclined block. A centering wheel is rotatably connected to the top of each curved rod. The centering wheel cooperates with the drive wheel. A telescopic component is provided on one side of the feed box.

[0007] Preferably, the telescopic component includes a rectangular block fixedly installed on one side of the feed box, a hydraulic cylinder fixedly connected to the bottom of the rectangular block, the telescopic end of the hydraulic cylinder passing through the rectangular block and extending to the connecting block, one end of the connecting block being fixedly connected to the lifting rod, and a matching stroke groove being provided in the fixed box near the connecting block.

[0008] Preferably, the conveying mechanism includes an oil tank fixedly installed on one side of the feed box, an oil pump is installed inside the oil tank, a conveying pipe is fixedly connected to the output end of the oil pump, the end of the conveying pipe away from the oil pump passes through the oil tank and extends to the nozzle, and the nozzle is connected to the conveying pipe.

[0009] Preferably, a regulating valve is fixedly connected to one end of the delivery pipe near the nozzle.

[0010] Preferably, the feed box is fixedly connected to several support frames near the conveying pipe, and the conveying pipe is engaged with the support frames.

[0011] This utility model has the following beneficial effects: Through the coordinated action of the chassis, chuck, shaft, ejector pin, feed box, cutter head, and anti-vibration mechanism, the device can not only provide support near the machined part of the shaft pin when turning it, thereby suppressing turning vibration and avoiding the phenomenon of tool vibration, but also eliminate the need for workers to manually install the center rest, saving the machining time of the shaft pin and improving the work efficiency of shaft pin machining.

[0012] Through the coordinated action of the chassis, chuck, shaft, ejector pin, feed box, cutter head, anti-vibration mechanism, and conveying mechanism, lubricating oil can be continuously sprayed at the support of the anti-vibration mechanism, thereby reducing the friction of the support point, preventing the device from scratching the turning surface of the shaft pin, ensuring the smoothness of the turning surface of the shaft pin, and improving the machining quality of the shaft pin.

[0020] This embodiment aims to facilitate a solution to the problem of how to avoid tool vibration during the turning process of the pivot pin. Please refer to [link to relevant documentation]. Figures 1-4A turning device for machining shaft pins includes a housing 1. A chuck 2 is mounted on one side of the top of the housing 1. A shaft 3 is disposed inside the chuck 2. The chuck 2 is used to clamp the shaft 3 and control the high-speed rotation of the shaft 3. A center pin 4 is disposed at the end of the shaft 3 away from the chuck 2. The center pin 4 is used to provide support force to the end of the shaft 3 away from the chuck 2. The center pin 4 is slidably connected to the housing 1. A feed box 5 is disposed on one side of the center pin 4. The feed box 5 is slidably connected to the housing 1. A cutter head 6 is fixedly connected to the top of the feed box 5. The cutter head 6 is used to fix the turning tool. An anti-vibration mechanism 7 is disposed on one side of the cutter head 6. The anti-vibration mechanism 7 can prevent the shaft 3 from vibrating during the turning process. A conveying mechanism 8 is disposed on one side of the feed box 5. The conveying mechanism 8 can spray lubricating oil on the surface of the shaft 3 supported by the anti-vibration mechanism 7, thereby ensuring the surface finish of the shaft 3.

[0021] The shock-absorbing mechanism 7 includes a fixed box 71 fixedly installed on one side of the top of the feed box 5. A lifting rod 72 is installed inside the fixed box 71. Two fixed blocks 73 are fixedly connected to the fixed box 71 near the lifting rod 72. The lifting rod 72 is slidably connected to the fixed blocks 73 and the fixed box 71, allowing for flexible vertical lifting and lowering between the fixed blocks 73 and the fixed box 71. A drive wheel 74 is rotatably connected to the top of the lifting rod 72. Inclined blocks 75 are fixedly connected to both sides of the middle of the lifting rod 72, with the inclined blocks 75 located away from the lifting rod. Each side of the rod 72 is provided with a crank 76. Both cranks 76 are rotatably connected to the fixed box 71 through a torsion spring. When there is no force applied, the torsion spring can keep the two cranks 76 in an extended state. The bottom of each crank 76 is rotatably connected with a driven wheel 77, which is coupled to the inclined block 75. The top of each crank 76 is rotatably connected with a centering wheel 78, which cooperates with the driving wheel 74. A telescopic component 79 is provided on one side of the feed box 5.

[0023] In this embodiment: The user fixes the shaft 3 between the chuck 2 and the ejector pin 4. After fixing, the shaft 3 is simultaneously located between the drive wheel 74 and the centering wheel 78. Then, the extension end of the hydraulic cylinder 792 is activated to extend outward and push the connecting block 793. The connecting block 793 drives the lifting rod 72 to rise. As the lifting rod 72 rises, it drives the drive wheel 74 and the inclined block 75. As the inclined block 75 rises, it pushes the driven wheel 77. The driven wheel 77 drives the crank 76 to rotate. As the crank 76 rotates, it drives the centering wheel 78, so that the drive wheel 74 and the two centering wheels 78 cooperate to support the shaft 3. This structure moves synchronously with the feed box 5, thereby providing support force near the turning part of the shaft 3 and achieving the purpose of suppressing turning vibration. Example
